xcode 8.3.1: Abort trap: 6 when compiling swift

Hi,

My project compiles fine in xcode 8.2.1 but when updating to xcode 8.3.1 several classes can't be compiled.

Error is Abort trap: 6 with stacktrace below, anybody experiencing the same?, This must be a compiler-bug, has anybody filed a bugreport?
